Back to the road again and my first choice for a search on route is this forum. I am pretty unsure if i can cover most of the state in 4-days.
Searching the forum ... AZBuck's Post #3 [specially US191] from the link below sounds very interesting.
Arizona on Motorcycle in 30 days
In addition, I have Route-66 in mind. [glc's Post #2 from the above link]
Do you have any suggestions on my trip ? [I am driving alone and am Ok with driving 600 miles a day]
